BMW X4 M40i Leaks Ahead of LA Auto Show

Leaked photos of the higher-performance BMW X4 M40i emerged today ahead of its expected debut at the 2015 LA Auto Show. The new model builds on the xDrive35i model, offering an extra 60 horsepower and 43 pound-feet of torque.

The hotted-up X4 should use that power well. According to Auto Guide, it will hit 62 miles per hour in 4.9 seconds and should be limited to a top speed of 155 mph – a notable improvement over the existing xDrive35i, which takes 5.2 seconds to hit 60 and has a top speed of 130 mph. Expect the X4 M40i to be followed by an similar version using the X3's more versatile body style, both of which will use an eight-speed automatic and a more aggressive all-wheel-drive setup.

Despite the "M" in its name, this is not a full-blown M car. Instead, it takes the same tack BMW has used for the M235i here in America, as well as the M50d models sold in Europe: higher performance over stock, without offering the full enchilada that is a proper M car.

That explains the slightly more aggressive body kit, which isn't as sporting as that of a proper M car. On top of the new front and rear clips, there's a set of meaty 19-inch wheels that look to be wrapped in sporty Michelin Pilot Super Sport tires. In the cabin, an oversized M-branded steering wheel is the most notable addition. Naturally, we'll have the full range of details on the X4 M40i when it debuts in a couple of months in LA.
